Advances in chip-scale photonic-electronic integration are enabling a new generation of foundry-manufacturable implantable silicon neural probes incorporating nanophotonic waveguid…
Microcantilever-integrated photonic circuits for broadband laser beam scanning
Saeed Sharif Azadeh, Jason C. C. Mak, Hong Chen +11
Laser beam scanning is central to many applications, including displays, microscopy, three-dimensional mapping, and quantum information. Reducing the scanners to microchip form fac…
Monolithically integrated, broadband, high-efficiency silicon nitride-on-silicon waveguide photodetectors in a visible-light integrated photonics platform
Yiding Lin, Zheng Yong, Xianshu Luo +8
Visible and near-infrared spectrum photonic integrated circuits are quickly becoming a key technology to address the scaling challenges in quantum information and biosensing. Thus…
Power-Efficient Silicon Nitride Thermo-Optic Phase Shifters for Visible Light
Zheng Yong, Hong Chen, Xianshu Luo +7
We demonstrate power-efficient, thermo-optic, silicon nitride waveguide phase shifters for blue, green, and yellow wavelengths. The phase shifters operated with low power consumpti…
Optical phased array neural probes for beam-steering in brain tissue
Wesley D. Sacher, Fu-Der Chen, Homeira Moradi-Chameh +13
Implantable silicon neural probes with integrated nanophotonic waveguides can deliver patterned dynamic illumination into brain tissue at depth. Here, we introduce neural probes wi…
Observation of photoelectric nonvolatile memory and oscillations in VO2 at room temperature
Youngho Jung, Junho Jeong, Zhongnan Qu +4
Vanadium dioxide (VO2) is a phase change material that can reversibly change between high and low resistivity states through electronic and structural phase transitions. Thus far,…
Pattern Formation in Double-Layer Kerr Resonators with Coupled Modes
Antoine Bois, Joyce K. S. Poon
A double-layer Kerr resonator in which both coupled modes are excited and interact with each other via incoherent cross-phase modulation is investigated to reveal stable localized…
Integrated Silicon Photonic Transmitter for Polarization-Encoded Quantum Key Distribution
Chaoxuan Ma, Wesley D. Sacher, Zhiyuan Tang +5
We present a silicon optical transmitter for polarization-encoded quantum key distribution (QKD). The chip was fabricated in a standard silicon photonic foundry process and integra…
Automatic Resonance Alignment of High-Order Microring Filters
Jason C. C. Mak, Wesley D. Sacher, Tianyuan Xue +3
Automatic resonance alignment tuning is performed in high-order series coupled microring filters using a feedback system. By inputting only a reference wavelength, a filter is tune…
Low-voltage broadband hybrid plasmonic-vanadium dioxide switches
Arash Joushaghani, Brett A. Kruger, Suzanne Paradis +3
Surface plasmon polaritons can substantially reduce the sizes of optical devices, since they can concentrate light to (sub)wavelength scales. However, (sub)wavelength-scale electro…
Breaking the cavity linewidth limit of resonant optical modulators
Wesley D. Sacher, William M. J. Green, Solomon Assefa +5
Microring optical modulators are being explored extensively for energy-efficient photonic communication networks in future high-performance computing systems and microprocessors, b…
